Reference grammar.
Uses antlr4 and a custom Rust tool to compare ASTs/token streams generated. You can use the check-lexer
make target to run all of the available tests.
To use manually:
antlr4 RustLexer.g4 javac *.java rustc -O verify.rs for file in ../*/**.rs; do echo $file; grun RustLexer tokens -tokens < "$file" | ./verify "$file" RustLexer.tokens || break done
Note That the ../*/**.rs
glob will match every *.rs
file in the above directory and all of its recursive children. This is a zsh extension.
